Sorry if this's been posted before (did some searching and couldn't find a topic like this), but this has been a question on my mind for a while, especially since I've noticed something about the way Alabama, Florida, and Tennessee do mileposts on non-freeways/Interstates.
Here in Alabama, ALDOT will sign mileposts for all state-maintained highways, even within incorporated cities and towns, starting from their southernmost/westernmost point within the state.
However, in Tennessee, non-freeways only have a little green sign that doesn't even say "mile" on it, just a number (with a smaller number underneath) that appears to reset at the county lines. Haven't noticed any of these within incorporated cities/towns either.
And in Florida, at least in the part of the Panhandle I've typically been in (and as such, can recall it the best), the only places I saw mileposts that weren't on an Interstate/freeway were on US 98 going through Tyndall AFB.
So I have to ask, does your state post mileposts along the state-maintained roads that aren't freeways and/or Interstates, and if so, then how are they done?
MN has mileposts on all state-maintained roads. One thing MnDOT will do on two-lane roads is post one double-sided milepost instead of separate assemblies for each direction.
WisDOT I think only mileposts freeways/expressways.
MA does some every 0.2, others every 1, and others not at all.
Some bridges get mile markers with 3 decimal places. Unlike typical mile makers, these must be perfectly accurate, so they might be slightly "out of order" compared with the rest.
If you look carefully, you might find an odd-numbered tenth marker, like 23.1, in a very small diamond. These are not meant for the general public.
NH usually doesn't. However, they do some of them every 0.2. They don't look like the ones in MA.
Louisiana signs mileposts on all state highways as well, but does not maintain them rigorously. They put up new ones approximately every 10 years. They only use the small u-channel posts (1.8 pounds per foot, whereas other highway signs use 2.6 pounds per foot posts), so they are easy to mow down with their bush hogs or can be easily pulled up & stolen. They are also posted in just one direction, unlike AL. DOTD has been using square tubing posts for their signs now in the last couple of years, but I haven't seen them used for mileposts yet (except for the interstates). I wonder if that will help them stick around longer? Any milepost bolted below another highway sign stays there forever unless knocked down by a car.
When I was a child...I have lived here in this house since birth...milepost 82 was always in front of my house across the road (US 80) at our mailbox. It had the old school mile marker of just a number on a green sign board (no "MILE" above it). Then on Dec. 11, 1985 (I remember the date written on the back), it was replaced with one that had MILE above the number. Ten years later, it was replaced...and moved west of my house about 400 yards. I pulled that sign up & put it back at my mailbox. Then in 2005, DOTD did it again. But before I could grab that one, someone stole it. I thought 2015 would bring them back with another batch, but they didn't do it.

MN has mileposts on all state-maintained roads.
I noticed an anomaly on MN-13...it goes from Mile 95 (just east of the exit to CSAH 5) to Mile 98 (about 1/2 mile east of 35W) in the span of 1 mile...did 13 get rerouted/truncated at some point by 2 miles?
I travel that route to Valleyfair on a weekly basis, and it always struck me as odd.
Florida also has mile markers on US 1 around Florida City, extending all the way down to its terminus in Key West. I think a few more US Routes have them, but except for other state/county limited-access highways or toll roads, that's about it.
Ohio uses them, and they reset at the county line (or route start/finish).
New York and Vermont have "reference markers", but someone more knowledgeable than me can probably explain them better.
Utah mileposts all numbered routes, every mile, no matter where they are. Unless the road is divided, that is done with a double-sided mile marker posted on the side of increasing mileage.
As part of the project several months ago to milepost all ramps through complex interchanges, I-80 is posted to the 0.1 mile through both of its interchanges with I-15.
All state routes in Georgia have mileposts, and with few exceptions (400 is the only one I can think of) they reset at county lines.
Note that US routes don't technically have their own mileposts; they're mileposted based on the underlying state route. As an example, for US 78 in DeKalb County, it starts out from 0 using GA 8's mileposts, resets to 0 again when it splits off onto GA 410, then picks up GA 10's mileposts when they join up in Stone Mountain.
NJ recently just signed all non-highway state routes with mileposts at the .0 and .5 locations. Previously, if they were signed, they were generally signed at the .0 mile point.
Quote from: 1NH usually doesn't. However, they do some of them every 0.2. They don't look like the ones in MA.
To clarify further, major routes like NH 16, US 2, US 3, and US 302 (to name some examples) have mileposts.

MN 13 originally followed Dakota Ave and McColl Dr through Savage. There was also the realignment related to the Mendota Bridge project in the early 1990s. The reference mileposts were fudged as a result of both.

As does Illinois.

For Vermont. (http://vtransmaps.vermont.gov/Maps/VTrans_RouteLogs/docs/Milemaker_info.pdf)
For states not mentioned yet:
In Pennsylvania, I've only seen them along US 6...and that was a tourism/marketing effort.
Virginia mostly lacks them except for some limited-access bypasses and US 13 on the Eastern Shore. It should be noted that, for the former, they do not use the mileage of the overall route but instead just the mileage of the bypass.
Hawaii mileposts (and sometimes also km-posts) most or all state-maintained routes. Some county routes are also mileposted.
Alaska mileposts all its numbered state routes, and many of its unnumbered state-maintained highways. However, its mileposts are based on named, rather than numbered, highways, so a traveler on a numbered route will see resets as it changes from one named highway to another. For example, from east to west AK 2's mileposts ascend to 1422 (mile 0 in Dawson Creek BC), then reset in Delta Junction to 266 and ascend again as AK 2 switches from the Alaska Highway to the Richardson Highway (mile 0 east of Valdez), then reset to zero and ascend yet again where the Richardson Highway switches to the Steese and Elliott Highways in Fairbanks. Most perplexingly, from west to east AK 1's mileposts descend from 171 to around 37, then start ascending again as the numbered route changes from the Sterling Highway to the Seward Highway (mile 0 for both in Seward) at Tern Lake Junction. So AK 1 has two MP 37s and 39s (not sure MP 38 is duplicated), as well as other duplicate MPs, on opposite sides of the junction. Those and other MPs are also duplicated as AK 1 changes from the Seward to the Glenn Highways, then to the Richardson Highway, then to the Tok Cut-Off, though at least those milemarkers ascend consistently from west to east.

Others in Virginia: VA 207 and US 301 from Carmel Church to the Potomac River, with US 301 using its distance from the NC line on its portion
US 17 from NC to I-64. This goes back to when it was US 17 and VA 104.
For some reason, US 460 west of Blacksburg has a few mileposts
Caroline and Essex Counties had them on all their primary routes but I'm not sure they still keep up with them (US 1's has numerous ones missing now) and they were not standard mile markers. Mileages were from county lines only.
SR 619 along the eastern edge of Quantico USMC base, for some reason.
VA 294 from Manassas south to Hoadley Rd, dates back to SR 3000 days and is in km.
VA 33 in each direction leaving West Point, in 1/2 mile increments and presumably to give an idea how long the backup was to the drawbridges that used to be there. I don't know if they are still there but were not removed immediately after new bridges were completed.

MA does some every 0.2, others every 1, and others not at all.
Some bridges get mile markers with 3 decimal places. Unlike typical mile makers, these must be perfectly accurate, so they might be slightly "out of order" compared with the rest.
Those bridge mile markers were erected during the mid-1980s and the practice of doing such was short-lived. As a result, on routes that since were re-aligned/modified (even slightly), the mile marker readings are either more out-of-synch at best or (worst case) not-in-synch at all with respect to the newer mile posts.
Examples (overpass-mounted (XX.XXX) mile markers only):
1. The ones along I-95 north of MA 128/Peabody reflect its pre-1988 extension & direct-connection to MA 128.
2. Likewise to #1, the ones along MA 128 treat 128's MM 0 at the US 1/S. Lynnfield interchange rather than at I-95/Peabody (I'm aware that the current 128 mile markers reflect its 37-mile concurrency w/I-95 from Peabody to Canton). One can just simply subtract 37 from 128's markers to calculate its
non-Interstate concurrency-based mile markers.
3. The ones along US 1 north of the Tobin Bridge reflect its pre-1989 re-route onto I-93 & 95 between Boston and Dedham.
4. Likewise to #3, the ones along MA 1A north of Logan Airport reflect the pre-1989 reroute of its US 1 parent via a silent concurrency.

Some NJ county routes also have mile markers in a style similar to what NJDOT used before the recent replacement (the new NJ mile markers have a shield on top of each marker, whereas the old ones did not). The usually haev whole miles only. There doesn't seem to be any rhyme or reason to which county roads have them and which don't.
Indiana has mileposts on most all INDOT-maintained state roads. On non-freeways, they use simple blue horizontal rectangles with white numerals and no other verbiage. A few can still be spotted along former state highways, such as Binford Boulevard in Indianapolis (former State Road 37).

Also on US 301 entering Charlton County from the north, instead of using US 301's mileage left to the FL State Line, it uses companion GA 23 that has a longer distance to its endpoint located north of Maclenny, FL. GA 23 splits from US 301 at Folkston and because of the bend in the St. Mary's River part of Georgia sticks into Florida making part of Charlton County have Nassau County, FL on one side of it with Baker County, FL on the other side. US 301 crosses between the states north of where GA 23 does so US 301 is shorter than GA 23 in Charlton County.
Florida only uses mile markers on US 1 in the Keys and US 27 now has them in Broward County. Most likely due to the lack of other routes crossing the two highways.
Delaware does not post its state routes. Seems to be in the minority based on what I've seen here.
NY 787 currently has regular tenth milemarkers in Cohoes even though it's a divided highway with traffic lights rather than a freeway. I do not know if there will still be any after the Cohoes Boulevard project is done, but I'm guessing not.

DE 1 is posted south of Milford in whole-mile increments...I think that is somewhat new, as I don't remember that being the case last summer.
The Tennessee example mentioned needs some translation. The larger number is the milepoint. The smaller number is the state route number. That's why on a route posted as a US route, the number on the mile marker won't match.
Kentucky signs its parkways with a continuous numbering system, from south or west terminus to north or east terminus, across county lines.
On other routes, mileposts reset at county lines.
West Virginia inconsistently posts mile markers on state and US routes, and they reset at county lines. I have not seen mileposts on the county route system.
Michigan, on US 2.
Iowa does. On expressways and freeways, they're identical to those you'd see on Interstates, while on 2-lane roads and city streets, they're smaller and omit the "MILE" word.

Usually based on the county itself- Hunterdon and Somerset will post all routes with a shield and milemarker, Burlington posts milemarkers on all routes, Ocean generally has just milemarkers on 500-routes, Mercer and Middlesex don't post anything.

MDOT added mileposts to both highways last year. The situation with US 2 was odd in that the western portion had smaller MPs for many years, but that scheme stopped between Iron Mountain and Escanaba (I think it was at the Dickinson—Menominee county line.) Local officials in Mackinac County had started adding mileposts running backwards from the eastern terminus. Those have been removed and replaced by the MDOT standard mileposts counting up from the state line at Ironwood. M-28 never had them, but it has a full set now, the full length from Wakefield to Dafter. If MDOT ever expands the concept to other highways, they'll need to replace the mileposts around here on US 41 to correct the direction of counting.
In North Carolina, freeways and interstates are generally the only milepost'ed roads. Although NC 181 has some, and that is a curvy two-lane mountain road. US 421 also has them on the way up towards Boone, but they stop around the top of the main incline.
Washington signs mileposts on all state-maintained highways, like so:

You forgot about the fiberglass/lollipop stick version they experimented with in the 1980s before briefly going back to the diamonds in the 1990s. *heh*
CA mileposts all state-inventoried highways, but these are done with small white paddles which reset at county lines. Generally these start at the southern/western terminus and proceed from there. Caltrans has never been convinced that a prominent display of statewide mileposts does much to improve navigation of state highway routes -- remember that they were quite late (the last 20 years or so) to post exit numbers on freeways, both Interstate and otherwise.
More about Massachusetts...
The diamonds date back to the 1960s originally AFAIK. They were rather small, and couldn't easily be read from a car (think the size of those little side reflectors on short posts on the side of freeways...in fact, they were designed to blend in with those).
In the mid 1970s, they tried something new...on divided highways, instead of posting the markers on the right shoulder, they decided to post them on the left shoulder of each direction, resulting in yellow diamond markers. This left-posting would be standard practice until the MUTCD conversion.
In the mid-1980s, they decided to make the "lollipop stick" versions, which were small reflective sheets posted on (first) fiberglass posts that were at first flat (with three-digit miles displayed in a diagonal pattern), then cylindrical (though wider at the top) with a cap on the top. The left-posting on divided highways continued (except, for some reason, on US-6 in Provincetown, which always struck me as weird...they didn't get left-posting until the next phase)
In the early 1990s, they went back to the diamonds, and around the turn of the millennium, they finally started using the MUTCD standard we see today.
During all that time, before the MUTCD era, they also painted the markers on the shoulders using traffic yellow paint. It was a yellow square divided in half with the whole mile on top and the fraction on the bottom (except for the .0, which said "MILE" on top and the whole number on bottom). Usually if it was just one lane each direction, they'd paint it on the North or Eastbound side facing perpendicular to the road, to be read from both sides. If it was 4 lanes or more, they'd paint it on both sides of the road facing the flow of traffic on each side. There were some exceptions (like MA-14), but the painting generally followed this rule until they went all-perpendicular in the 1980s.
And that's MA's weird history with mile markers
AFAIK the only non-freeway in Pennsylvania with mile markers is US 6 with its fancy mile markers:
(https://pbs.twimg.com/profile_images/555820322939629568/7Dc1yY-F.jpeg)
The only non-freeway road I know of in Maine that uses mile markers is the segment of ME 9 east of the Bangor/Brewer area out toward Calais. There isn't much along that portion, plus it's relatively well traveled, so it makes sense as to why MaineDOT chose to post them there.
ODOT does, but they're based on the Highways, not signed Routes. Routes like 140 will see several Mile 1 mileposts.
Two exceptions: Highway 53 (US 26) continues Highway 26's mileposts from where OR 35 splits off US 26, and Highway 6 (I-84) continues on with Highway 2's where US 730 splits off.
CT: Yeah, right. The Land of Steady Habits had to be dragged in kicking and screaming in the 90's to add mileposts to limited access highways, including state routes. Only roads with mileposts are I-84, I-91, I-95, I-395, I-684 (by NYSDOT) the Norwalk portion of US 7, CT 2, the standalone portion of CT 2A, CT 8, CT 9, CT 11 (! And based on unbuilt mileage), CT 15 Parkway portion only, and CT 25. No other non-limited access routes have mileposts, nor does I-291, I-384, I-691 or any limited access portions of other US and state routes. Areas without sign updates still have the original mileposts, and many are either illegible or missing.

Nevada mileposts all state highways using a style and method similar to California's postmile system. Posting of mileposts is much more consistent in rural areas; in urban areas, mileposts tend to be placed at signalized intersections but not at mile locations.
Here's a thread on the Pacific Southwest board about Nevada's new milepost style (https://www.aaroads.com/forum/index.php?topic=13429) from circa 2015.

WI does not milepost 2-lane roads. They do have select non-freeway 4-lane roads mileposted, but not all:

*US 151's mileposts end just a few miles short of Hwy 41.
*US 45 toward West Bend is is not mileposted.

The white paddles sparker is referring to are called "postmiles" and they include a county name abbreviation ("SCL" = Santa Clara County) and the route number in addition to the mileage from the county line. As far as I know, all numbered highways have postmiles.

While this is true, Caltrans did dabble in posting mileposts (or Reference Location signs) on a portion of CA-58 between Bakersfield and Mojave and on US 6 between Bishop and the Nevada stateline. However, they were all removed a few years ago. I recall hearing one of the reasons why they were removed was because they caused confusion when it came to reporting incidents like accidents or debris in the roadway.

That is correct. On certain roads where flexible delineators were provided, the milepost was printed on the delineator as well. This was tried on a few projects in what is now District 5, but was never expanded to the rest of the state. Remember that this was the era where intermediate mileposts (the diamonds) were provided for planning and maintenance purposes, and were never intended to be viewed by drivers.
Why does California call them "postmiles" and not "mileposts?" I have never seen a logical definitive answer for this.
NC 12 has some mileposts, though not very consistently. I have yet to see any in South Carolina
Answering for states around me:
KS: all signed state-maintained routes have mileposts counting up from origin or south/west state border; MUTCD milepost design is used on expressways/freeways, while a KDOT "numbers on stick" design is used on conventional roads
MO: only Interstates have milemarking and enhanced location reference markers at 0.2-mile spacing are typically used in lieu of MUTCD mileposts
CO: all state-maintained routes have mileposts to the MUTCD design
NE: similar to KS, except "numbers on a stick" are used on non-Interstate expressways/freeways
OK: Milemarking provided only on Interstates and turnpikes (MUTCD design for both)

Yes, they are, though the system is (AFAIK) far from universal. The milepost "paddle" is in the Illinois
SHS supplement. The basic design is green circle with green horizontal crossbar on a white square, with the county name on the crossbar in white and the mileage (to tenths) in black in the bottom part of the circle. I recall roads like SR 29 and SR 26 north of Peoria and SR 3 in East St. Louis having markers like this, but not US 24 between Indiana and I-55.
Rhode Island has mileposts on I-295 and RI-146 and RI-99 (I think RI-4 as well). Some of I-95 is mileposted, but it is largely spotty.
US-6 is mileposted only on the freeway segment (with the zero milepost at the I-295 junction, so it dos not count most of the route). The mileposts then reset at the RI-10 junction, with the 6/10 overlap having its own mileposts with zero at the Olneyville merge and ending at the I-95 interchange downtown. These are also separate from another set of mileposts on the independent section of RI-10.
None of the secondary roads are mileposted.
From GSV, I-95 in RI looks pretty well mileposted with 2/10 mi posts. And despite having some ancient signage, RI 78 is well mileposted, with Mile 0 being in the center of the Pawcatuck River bridge at the CT line. Looks like RI 403 is also done, as is the portion of RI 10 south of US 6. I-195 has whole mile MUTCD posts only, and RI 24 has mileposts that are about 4 miles off from the actual length of the built portion. RI 37, the TF Green Connector, and the Jamestown portion of RI 138 between US 1 and the Newport Bridge, have no posts at all.

Why does California call them "postmiles" and not "mileposts?" I have never seen a logical definitive answer for this.
I think it's to avoid confusing the black-on-white postmiles with the MUTCD-standard white-on-green mileposts used by the rest of the country.
Meanwhile in Nevada, which uses the same basic system as California, the black-on-white version is referred to as a "milepost" and the white-on-green version (used on Interstates only) is referred to as a "(enhanced) reference panel" in official documents. (Curiously, the green version is referred to as a "post mile" on NDOT's webpage explaining mileposts...)
Note that the MUTCD calls the green version "(enhanced) reference location signs", with the term "milepost" not appearing in the document.
Maryland generally doesn't install mileposts for non-divided state highways. One of the few routes that does have mileposts is MD 23 between MD 165 and US 1. Another one is US 220 between I-68 and the Mason-Dixon Line.

Where is/was this old South Shore Tunnel that you speak of?
It's what traffic reporters used to call the original central artery tunnel (which was I-93 between I-90 and Atlantic St.) because it was considered the "gateway" to the South Shore. Parts of that tunnel were used for the underground ROW of the southbound lanes of the current artery tunnel.
Edit: South STATION Tunnel...dear zapfish, I feel dumb now...

I had a hunch that you were referring to the old South Station Tunnel (originally referred to as the Dewey Square Tunnel) but wasn't 100% sure.
Truth be told & IMHO, the "Gateway" to the South Shore was actually at the location of the Mass Ave. interchange (especially in its original pre-Big Dig configuration). This was where I-95 was originally planned to leave the Fitzgerald Expressway via a portion of the Inner Belt plus the Southwest Expressway. Contrary to popular belief, this is the actual location of the northern terminus of the Southeast Expressway. The portion of the Fitzgerald Expressway viaduct between Mass Ave. & the South Station Tunnel
was called the Pulaski Skyway. Small white signs bearing the Pulaski Skyway name were along the median. Needless to say, that name never fully caught on.

The only non-freeway road I know of in Maine that uses mile markers is the segment of ME 9 east of the Bangor/Brewer area out toward Calais. There isn't much along that portion, plus it's relatively well traveled, so it makes sense as to why MaineDOT chose to post them there.
I have noticed that, and I wish MaineDOT would use mile markers on some other state or US routes, especially US 1.
COLORADO: Nearly all state & US highways (excluding some urban areas) use the standard white-on-green mile markers.
Many of the primary county highways in Western Colorado use some sort of mile marker and there are county roads where the home and business addresses are based on the mile markers.
(i.e.: If an address was 17200 CR 417, the address would be located between MM 17 and 18, or 17.2 miles into CR 417.)
In Harford County, Maryland, the U.S. 1 Bel Air/Hickory Bypass has mile markers based on the distance from the Baltimore County line. Maryland Route 23 also has them between U.S. 1 and MD-165.
